C＃Spotify自动登录。获取授权码

Question

对不起，英语不好。 :) 我想使用Windows IoT制作rasberry pi spotify播放器，并使用Spotify Web播放SDK。 但是首先，我必须从spotify api授权代码中获取一个令牌。 为了获得授权码，我必须先登录才能进行Spotify。 我正在尝试模拟发送到Spotify服务器的数据包。但是我总是得到答案“ {\“ error \”：\“ errorInvalidCredentials \”}“ 我在做什么错你能帮忙吗？

这是我的代码：

  public class SpotifyApi
{
    string clientId = "------------------------";
    string clientSecret = "--------------------";
    string redirectUri = "https://localhost:8888";

    string authorizeUrl = "https://accounts.spotify.com/authorize/?client_id=-------------------&response_type=code&redirect_uri=https://localhost:8888";
    string loginUrl = "https://accounts.spotify.com/api/login";

    string csrf_token = "";

    public async Task<string> Authorize()
    {
        HttpClient client = new HttpClient();
        HttpResponseMessage response = await client.GetAsync(authorizeUrl);
        foreach (var header in response.Headers)
        {
            if (header.Key == "Set-Cookie")
            {
                var key = header.Value.ToArray();
                csrf_token = key[0].Split(';')[0].Split('=')[1];
                IEnumerable<KeyValuePair<string, string>> loginValues = new List<KeyValuePair<string, string>>()
                {
                    new KeyValuePair<string, string>("csrf_token",csrf_token),
                    new KeyValuePair<string, string>("username","----------"),
                    new KeyValuePair<string, string>("password","-----------"),
                };
                HttpContent content = new FormUrlEncodedContent(loginValues);
                client.DefaultRequestHeaders.Referrer = new Uri("https://accounts.spotify.com/en/login?continue=" + authorizeUrl);

                var rezult = await client.PostAsync(loginUrl, content);
                string rezultString = await rezult.Content.ReadAsStringAsync();


            }
        }



        return "";
    }
}
